I got certified in Feb. Bought my Mosquito, got 17 dives on it, and one evening (Just after my advanced class beginning of May) in my computer room <beep>. Told me I was at 16 feet. Tried everything, but the next morning, it told me I was still at 16 feet (for 800 minutes, no less).
Sent it in, got a new one back day before yesterday (they replaced instead of repaired). I was happy about that, until I got it home. Backlight was screwed up. Would only flicker for a few seconds, then nothing. Took it back.
Thinking seriously about the dive-rite wrist computer. I was really sold on the mosquito (a DM friend has had a stinger for several years now with no probs), but I'm not entirely comfortable with Suunto computers anymore.
So. after 20 dives, I'm on my third mosquito, with one not even getting wet (not even in the shower :upset: )
